Systems Marginal Cost Curve and Its Applications
نویسندگان
چکیده
This paper presents a forward recursive procedure to calculate the expected system marginal cost curve (EMC). The EMC formulation allows for multi-state and multi-block dispatch of generating units and is used to determine the optimal energy of pumped-storage units. A new approach is developed to compute the first and second derivatives of the expected generation energy of a thermal unit with respect to the capacity of all thermal units in the system. The salient feature of the proposed approach is that it applies to hydro-thermal systems with multiple limited-energy hydro units. Keywords-Marginal Cost Curve, Pumped-Storage Units, Probabilistic Power System Dispatch, Derivatives in Probabilistic Production Cost, Emissions Control

Inflation Dynamics in a Dutch Disease Economy
Abstract In this paper, the effect of foreign sector macro-variable on inflation dynamics and firms’ pricing behavior has been investigated in the context of a small open economy New Keynesian Phillips Curve. This curve is derived and estimated for a developing oil-exporting economy suffering from Dutch Disease. This version of NKPC is an extension of Leith and Malley’s (2007) small open econom...
متن کاملTransmission Cost Allocation in Restructured Power Systems Based on Nodal Pricing Approach by Controlling the Marginal Prices
This paper presents a method to allocate the transmission network costs to users based on nodal pricing approach by regulating the nodal prices from the marginal point to the new point. Transmission nodal pricing based on marginal prices is not able to produce enough revenue to recover the total transmission network costs. However, according to the previous studies in this context, this met...

With the development of deregulated power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benefi...
متن کاملEstimating the Marginal Abatement Cost Curve of CO2 Emissions in China: Provincial Panel Data Analysis
This paper estimates the Marginal Abatement Cost Curve (MACC) of CO2 emissions in China based on a provincial panel for the period of 2001-2010. The provincial marginal abatement cost (MAC) of CO2 emissions is estimated using a parameterized directional output distance function. Four types of model specifications are applied to fit the MAC-carbon intensity pairs. The optimal specification contr...
متن کاملReversible Logic Multipliers: Novel Low-cost Parity-Preserving Designs
Reversible logic is one of the new paradigms for power optimization that can be used instead of the current circuits. Moreover, the fault-tolerance capability in the form of error detection or error correction is a vital aspect for current processing systems. In this paper, as the multiplication is an important operation in computing systems, some novel reversible multiplier designs are propose...
